How much condensation should you get on the main cold water inlet to the house? Sometimes it's dripping off the stoptap but not a constant drip, just there is water there that looks like its ready to drip.
Also when removing part of a kitchen unit today where the pipe goes into the concrete floor there is a lot of the green stuff growingand the pipe looks damp as does the concrete around it.
